If you are just wanting alittle more sound out of the bike that will work.Use to use a long ladies foot bar and knock 3 holes in the baffle plate when you look up the end of muffler.Would suggest you remove mufflers before trying this though had a friend that left mufflers on and it sucked a piece up into the head.
Smitty has it right been there done that they sound terrible, if you want inexpensive try cycle shack a lot of bang for your buck plus u can change the baffles to Big City Thunder and get better sound and performance
